Patent DE-3483404-D1 (DE)

Abstract: A method for making drip irrigation lines comprises feeding an elongated sheet of flexible polyethylene film to an injection molding machine for injection molding a series of drippers across a face of the film. A moldable thermoplastic material is injected into multiple die cavities, forming separate drippers each simultaneously heat-bonded to the film. Each dripper has a molded labyrinthine flow-restricting passage extending along it. The mold is opened, the film is advanced, and further series of drippers are injection molded across the face of the film. The previously molded set of drippers are closed off by heat sealing a separate strip of flexible film to a face of each molded dripper to form sealed internal pressure-reducing labyrinthine passages in the drippers. An inlet opens into one end of the sealed internal passage and an outlet opens from the opposite end through the film. The outlet is formed and reinforced during the molding process. A second layer of film is overlayed on the sealed drippers and on the film onto which the drippers are heat-bonded. The second film is bonded to the other film along parallel seams between the drippers, and the film is then cut along the seams to form multiple continuous drip irrigation supply tubes with the molded drippers being spaced apart along the inside of each supply tube.

Abstract: A position measuring system for measuring the relative position of two objects movable with respect to one another includes a housing which rotatably supports a shaft connected with the first object. A first graduation disk with a first incremental graduation and at least one absolutely positioned first reference mark is mounted to rotate with the shaft. A first scanning unit for the scanning of the first incremental graduation and the first reference mark is rotatably mounted on the shaft to rotate relative to the first graduation disk and the housing. A second graduation disk is firmly connected to the first scanning unit. The second graduation disk defines a second incremental graduation and at least one absolutely positioned second reference mark. A second scanning unit is fixedly mounted to the housing which is connected to the second object. In order to reproduce a reference position after an interrupted measurement operation and unknown movement of the relative position of the two objects, the first scanning unit is rotatable together with the second graduation disk for the scanning of the first reference mark of the first graduation disk and for the scanning of the second reference mark of the second graduation disk. The distance between the two reference marks is counted in a differential counter.

Abstract: A crystal controlled reference oscillator (20) has two outputs (3,20) 180 degs. out of phase and fed to two identical phase comparators (5,22). A synchronising signal (6) forms the second input to the comparators. The resulting phase difference signal from the first comparator is passed, via a low-pass filter (12,13), to the control signal output terminal (10). The second comparator generates a polarity signal (24) from the phase difference of the reference and the synchronising signal. This is passed to a non inverting amplifying limiter (26) whose output (27) is added to the phase difference signal from the first comparator, the signals beinq balanced by a variable resistor (20). This cancels phase related components in the control signal.

At a point some way away from this end, there is provided, either on this blade (1) itself, or on the fixed contact part, a boss or other relief (15), the arrangement being such that when the blade (1) rocks in the direction of closing, contact is established firstly at the location of this boss, then also at the end of this blade, and finally only at the end of the latter. When rocking in the direction of opening a reverse process occurs, separation of the contacts taking place at the location of the boss or other relief (15) provided either on the rocking blade (1), or on the fixed contact part. Thus, closure and disconnection take place at a point distinct from the final areas of contact between the connection parts, so that these areas are sheltered from the effects of disconnection and closing arcs.
